Filed Sept. 14, 1939 l 2 Z q n Patented June 2, 1942 v i HORN MOUNTING Peter C. Beck, Adrian, Mich, assignor to Schwarze Electric Company, Adrian, Mich., a corporation of Michigan Application September 14, 1939, Serial No. 294,935

1 Claim.

This invention relates to detracting from vibration disturbance of sound producers.

This invention has utility when incorporated in diaphragm types of horns, especially for mo tor vehicles with advantages in the mountings hereunderto avoid or minimize undesirable influence arising from operation of such structure in its assembly.

Referring to the drawing:

Fig. l is a side elevation of an embodiment of the invention for a motor vehicle horn or signal;

Fig. 2 is a section on the line II--II, Fig. 1, showing the mounting features therefor;

Fig. 3 is a side elevation of a twin hcrn structure having features of th invention therein;

Fig. 4 is a view on the line IV-IV, Fig. 3, showing rearward support from the loops of the mounting structure;

Fig. 5 is a further detail of the mounting in plan supported on a rod from a plate between the loops of thebracket for the horn pair of Fig. 3; and

Fig. 6 is a section on the line VI-VI, Fig. 4, showing detail features of the mounting.

Mounting or support I maybe a place exposed for upward horizontal, lower horizontal, or'vertical side face as a motor vehicle body or chassis which may have bolt 2 therefrom, having washers 3, 4, providing gripping faces for any angle engagement through opening 5 in strap having straight or fiat portion 6, with similar bows '1, 8, outward to complementary bows 9, I0, inward. The bow 9 has straight portion II providing concave face I2, anchored by brazing, soldering or welding I3 with trumpet I4. From the curved portion I there is oppositely extending straight portion I having concave seat I6 anchored by weld, braze or solder I1 and spaced by the anchorage from the portion II. These 40 two anchorages with the trumpet I4 are not only spaced from each other but spaced from housing I8 having therein diaphragm I9 adapted to be actuated by electromagnet 20, energizing current for which is supplied through line 2|. This strap mounting as flatwise transversely of the direction of the trumpet I4 is adapted for rigidly supporting the horn against strains or shocks transversely or widthwise of this strap mounting. There is thus an eiiiciency of operation under that contemplated for the equipment and the take-up is in the bow. portions 1, 9, and 8, I0, as functioning cooperatively to respond to the shock,

This general end 21, 28, as an anchorage pair engaging the rein response to operations hereunder.

turn bend or U-portions at the different legs thereof and accordingly spaced from each other.

The loop portion of the mounting between the portions 21, 28, is shown to comprise straight section 29, corner 30, straight section 3|, corner 32, straight section 33, corner 34, to straight section 35. Bolt 36 may mount strap 31 between the straight portions 23 in providing deck 38- for mounting relay 39, whereby push switch 49 may cut in current from battery4l for the desired sounding or functioning of the horn. Bolts 42 through the straight portions 33 may mount plate 43. (Fig. 5) providing mountings for clamps 45,

thereby adapting the device to be mounted on rod 46 from the dash say to the motor. This would leave the fiat portions away from this deck 43 in position for flexing as to this anchorage or mounting. In this instance there are the spaced anchorages 21, 28, with the respective trumpets and away from the housings for such trumpets.

Additional or independent mounting may be effected for the deck 43 having ear 41 (Fig. 3) directed toward ear 48 from the deck 31. Through these ears 41, 48, bolts 49 may mount the twin horns on a vertical wall under the hood say as on the motor side from the instrument board or panel, or under the cowl. With both brackets 41, 48, anchored by a bolt 49, there is more rigidity than with the use of but one thereof. This leaves the flat region 3| between the mountings as sufficient for more or less flexin The straight portions 3I adjacent the bends 39, 32, have openings 50 which may be engaged by bolts 5| as in washers 52, similar to the bolt 2, thereby allowing the intermediate straight portions 3|, as away from the mounting, to flex somewhat.

The strap mounting for each trumpet takes up actuator vibration independently of external of single holding strap mountdisturbance. Furthermore, the mounting tends This plate 43 has openings 44 to suppress or dampen external vibration against disturbance of the function of the horn.

What is claimed and it is desired to secure by United States Letters Patent is:

A sound projecting device for use on an engine-driven vehicle, the device embodying a housing containing a diaphragm and means for actuating this diaphragm, a trumpet section extending outward from the housing, a mounting for the projecting device having a pair of spaced anchorages along the trumpet section at diflterent distances from the housing, this mounting including a flat spring leaf member having its fiat portion transversely of the axis of the trumpet section, the length of this member being substantially in alignment with the trumpet section, this member having bent portions in it to provide greater resiliency, each end of this member being attached to one of the anchorages and an intermediate portion of this member being at- 10 ta-ched to a fixed support.
